Comment 3 for bug 1764264

As near as I can tell, the cloud-init lines:
2018-04-16 07:14:36,809 - util.py[WARNING]: Running module apt-configure (<module 'cloudinit.config.cc_apt_configure' from '/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py'>) failed
2018-04-16 07:14:37,036 - schema.py[WARNING]: Invalid config:
...

Are just warnings and not actually failing. Certainly the script itself seems to be run.

It does seem like a cloud-init schema validation bug if it wants to claim that you can't repeat the same content in "runcmd".

Consider a script like:

if [ $a == "a" ] ; then
  a()
fi
if [ $b == "b" ] ; then
  b()
fi

In that case you'll have 'fi' repeated 2x, and trigger the same failure.

I think both 'runcmd' and 'bootcmd' should be allowed to have duplicate entries.
